20 apps that hardcore iPhone fans can't live without

Apple's iPhone had a huge impact on the industry right out of the gate since it prompted a shift toward the touch-centric smartphone experience we all enjoy today, but the iPhone's real game-changer came a year later courtesy of the App Store. By moving app portals off of the web and onto the device itself, Apple brought apps to the masses, allowing users to completely alter the iPhone's capabilities with just a few quick taps. The app market took off from there, and it has since grown into a multibillion dollar business as well as the most important part of the smartphone experience.

As big as mobile apps have become though, the App Store is flooded to the point where finding great apps is quite difficult. We do our best to help by drawing attention to the top apps we come across and by publishing a very popular series on paid apps that go on sale for free. Now, it's time to see which apps hardcore iPhone fans say they can't live without.

In a thread on Reddit in the iPhone subreddit, user Lev-J asked other redditors a simple question: "What apps can't you live without?"

Every iPhone and iPad user has different wants and needs, but it's always a good idea to pay attention to threads like this, especially when they garner a healthy number of responses. In this case, there were more than 370 responses at the time of this writing.

I dug through as many of the responses as I could, and I've compiled the 20 app suggestions with the most up-votes here in this post. You'll find them listed below along with links to download each one.
